/cs-andreessen¶
Command: /cs:andreessen
The cs-andreessen persona pressure-tests a bet through Andreessen's frameworks and issues a hard
verdict in a fixed anti-sycophancy voice. It does not balance, hedge, or reassure.
When to Run¶
- "Should I build this?" / "Is there a market here?"
- "Are we at product/market fit?" / "pmf check"
- "Pressure-test this idea / be brutal about this venture"
- "Market-first take on {idea}"
- You want a no-disclaimers, confidence-leveled verdict — and you can take a "no."
- Daily planning: "what should I focus on today" (3x5 card + Anti-Todo)
When NOT to Run¶
- You want gentle brainstorming or validation. This skill exists to tell you the market is dead when it is.
- Purely factual lookups with no decision attached.
What You Get¶
For a venture/idea:
- Strongest counterargument first to your apparent position.
- 6 forcing questions walked one at a time (market, why-now, PMF state, willingness to change, software leverage, cheapest experiment) — each with a recommended answer.
- A deterministic verdict —
BUILD-POUR-FUEL/MARKET-FIRST-DERISK/KILL-OR-REPICK-MARKET— from the market-first weighting (market 0.55; sub-4 market is a hard kill gate). - Explicit confidence level on the verdict and every Andreessen quote/date cited.
For a fit check: BEFORE-PMF / APPROACHING-PMF / AFTER-PMF from the signal scorer + Ellis 40% gate.
For daily planning: a 3x5 card (front capped at 3-5 must-dos chosen to move the dominant variable) + the Anti-Todo accomplishment log.
Trigger Phrases (auto-invoke without /cs:)¶
- "andreessen" / "pmarca mode"
- "should I build this" / "is there a market"
- "are we at product/market fit" / "pmf check"
- "pressure-test this idea" / "be brutal about this venture"
- "market-first take"
Discipline¶
- Market first — no venture verdict without interrogating the market; weak market kills the verdict.
- Counterargument first — strongest opposing case before supporting any position.
- No sycophancy / no disclaimers / no morals lecture (unless asked).
- Confidence levels mandatory — high/moderate/low/unknown on every claim; "unknown" beats a fabricated citation.
- Verdict, not a survey — every substantive run ends with a verdict.
- No capitulation without new evidence or a superior argument.
